IIVIPROVED RULE-CLAMP.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern.-

Be it known that I, 1). H. STEPHENS, of Riverton, in

the countyof Litchfield, and State of Connecticut, have invented a new and improved Rule-Clamp; and I do hereby declare that the following is a full, clear, and

exact description of the same, reference being bad to the annexed drawings, making a part of this specific-ation, in which-- Figure l is a side view.

Figure 2, an edge view.

Figure 3, also a side view, showing the rule-pieces and joint in their proper positions, and the manner in which the end and side-pressure is produced upon the joint of the rule.

Figure 4 shows the forked piece, with the bevelled jaws attached.

The object of this invention is to provide an improved device for pressing the metallic joints of mechanics rules tightly against the wooden portion, so that in drilling the rivet 0r pin-holes, and inserting the pins which hold the parts together, a perfect seating of the joint is obtained, to render it firm and secure within the rule.

The operation of the clamp is as follows:

The rule A is placed in the forked piece B, with one end against a stop, 0, and the other (with the joint) be:

- Claim.

As anewarticle of manufacture, the rule-clamp herein described, consisting of the forked piece B, having the stop 0 and bevelled jaws a, the clamp-frame D, screw b, and nut c, all constructed, arranged, and operating, as herein described, for the purpose specified.

The above specification of my invention, signed by me, this 19th day of January, 1866.
